IMPROVEMENT IN HOSE-COUPLING FAUCETS.FOR'BEER-FERMENTING VESSELS.

Specification forming part of Letters Patent No. 210,209, dated November 26, 1878; application iiled November 4, 1878.

l To all whom it may concern:

Be it known that I, J onN M. PFAUDLER, of Rochester, in the county of Monroe and State of N ew York, have invented a new and useful Hose-Coupling Faucet for Beer-Fermentng Vessels, of which the following is a specification:

My invention relates especially to the apparatus for fermenting beer described in Let.- ters Patent No. 205,572, issued to me July 2, 1878, its object being to provide a simple device which will enable the attachment and detachment to the same branch hose of one of the section-pipes of several barrels or other The accompanying drawing represents a' longitudinal vertical section of my couplingfaucets in position for use.

A and B are two stop-cocks with tapering shanks al bl, and turning` conical valve-plugs a b, arranged at right angles to the passage or pipe. The shank a1 is threaded, so that it may be screwed into a hole through one -of the upper staves of a barrel or other fermentin g-vessel, D, and thus the cock A may be secured to the said vessel. The shank 111 is grooved or corrugated around its surface, in order that, when inserted in the end of a hose, E, Whose other end is connected to one of the pipes of the fermenting apparatus, it will afford a better hold for the cord With which the hose is Wound to the shank. The

outlet end of the cock A is a threaded nipple, a2. The inlet end of the cock` B is a nipple, b2, provided with .the surrounding end flange b3.

C is a thimble, threaded on the inside to t the thread around the nipple a2, and provided with the inward flange c, by which latter it surrounds the nipple b2, and rests upon the flange b3, so that it can be turned upon but not detached from the nipple b2, and when screwed down upon the nipple a2 will tighten the ange b3 upon the end of the nipple a2, a packing-ring, F, being interposed, and thus secure the two .cocks A and B together in a manner Which will prevent leakage, while allowing of a free flow of gas from the vessel D to the hose E when the valves a b are open, as in the drawing.

To prevent the escape of gas while'replacing the vessel D by another provided with a similar cock, A, it is only necessary to close t the valves a b before unscrevving the thimble C. Upon the castings A B C are formed polygonal flat surfaces a3 b4 c', to afford hold for Wrenches in connecting them.

Having thus described my invention, I do not claim separately either the stop-cocks, whether with threaded or corrugated taper shanks, or the ordinary thimble-coupling C a2 b2; but

What I claim as new, and desire to secure by Letters Patentis lhe combination of the stop-cock A, havin g threaded taper shank al, andthe threaded nipple a2 with the stop-cock B, having corrugated taper shank b1" and the iianged nipple b2, and with the threaded and iianged thimble C, substantially as and for the purpose set forth.
